8 Claims.

The object of this invention is to provide an improved printing mechanism for registers in which it is desired to print two or more duplicate impressions from printing wheels. Means are also provided whereby the impression may be taken on either a record strip or an inserted slip. We also provide means to space the stock of paper between the various impressions and have provided means so that the paper would be spaced a certain distance between the double impressions and a different distance when the next registration is to be made. Means is also provided to render the printing mechanism inoperative if desired.

In the drawings:

Figure 1 is a side elevational view taken through the register, certain of the parts being shown in cross section;

Figure 2 is an end elevational view;

Figure 3 is a detail elevational view of the shifting lever and box cam controlled thereby;

Figure 4 is a side elevational view of the driving disk shown in Figure 1; and

Figure 5 is an end elevational view of the structure shown in Figures 3 and 4 and the parts associated therewith.

An on and off lever is pivoted on a shaft 2. This lever is providedwith a pin 3 on which is hung a link 4 which carries a pin 5 at its lower end connected to a lever B secured to a shaft 1. A lever B is also secured to the shaft 1 and for all practical purposes the levers 6 and 8 might be considered as one lever. At the end of the lever 8 remote from the pin 5 is a pin 9 which rides in a cam channel It in a lever I mounted on a shaft 2. The lever I is secured to a lever l3 by means of a yoke member I4. The lever I3 is provided with a pin I5 which is operatively connected to a lever I6. The lever i6 is provided with an upstanding arm I! which is bifurcated to receive a shaft I8 which holds the lever it against rotation. The lever l6, as shown in Figure 3, is provided with an outstanding lug I9 which may be moved into or out of a radially extending slot 20 in a box cam disk 2|. When the on and off lever is in the position shown in Figure 1, which is its off position, the lug I9 extends within the slot 20 of the disk 2| and locks the disk against rotation so that the printing which will hereinafter be described cannot take place. If the lever I is rotated clockwise, however, to its on position, the link i will be lowered, which will rotate the levers 6 and 8 anti-clockwise, raising the pin 9 in the cam channel [ii and rotating the levers l and I3 in a clockwise direction, pulling the lever I6 upwardly and to the right as viewed in Figures 1 and 3 and removing thelug l9 out of the radially extending slot 20 in the disk 2| so tha the said disk is free to rotate.

The lever I6 is provided with a circular cutaway portion 22 which receives a disk 23 provided with a slot 24 and a radially extending lug 25. is a part of the disk 2 I.

Within the slot 24 is a bifurcation 26 which As the lever 93 is moved extending slot 2|] in the said disk so that the 2| and the disk 23 are locked together.

disk

the

disk 23 will be concentric with the shaft 2i, which is the main drive shaft for the machine.

Both of the disks 23 and 2| are loosely mounted on the drive shaft 21 but a disk 28 is secured thereto, which disk has outstanding lugs 29 between which may be received the lug 25 carried by the disk 23 sothat if the lever I is shifted to its on position, the lug 25 not only engages the bifurcation 26 on the disk 2| but also it extends between the lugs 129 on the disk 28 secured to the main drive shaft so that the disks 23, 2| and 23, will now rotate as a unit with the main drive shaft.

The box cam disk 2| is provided with a box cam 30 shown in dotted lines in Figure 1. cam is provided with lobes 3| and 32.

This

box

The lobe repeat this process.

If it is desired to repeat it a third time, a third lobe cam would be used. Since the main drive shaft makes one revolution for each operation of the machine, it, of course,

follows that the box cam 30 and the lobes 3| and 32 make one revolution for each operation of the machine. mounted on a pivot pin 34 carried by the walls of the machine.

An ink roll operating arm 33 is side This operating arm' 33 carries a pin 35 on which is mounted a roller 33 which extends within the box cam 33. This arm 33 is secured to a shaft 3'? to which is also secured an arm 38 provided with a semi-circular cutaway portion 39 which engages one side of a shaft 40 on which is mounted an ink roll 4|. Guide arms 42 are also pivoted on the pivot pin 34, which arms carry the shafts 3! and all.

The

only function of these guide arms is to prevent any whipping or side turning of the shaft 40.

When the 1 lever I has been moved to its on position,

the box cam 30 is rotated anti-clockwise as shown in Figure 1 the roller 36 will be actuated by the lobe 3| so as to move the ink roll operating arm 33 in a. clockwise direction and move the ink roller 4| beneath the printing wheels 43. As soon as the lobe 3| has passed the roller 36 the outer wall of the box cam will return the ink roll 4| to its position as shown in Figure 1. The lobe 3.2 will, of course, repeat this process but after each time that the ink roll 4| inks the type 43 a printed impression will be made on the paper stock as will now be described.

A lever 44 is mounted on a shaft 45 and has a downwardly extending arm 46. The upper end of the lever 44 carries a pin 41 on which is mounted a roller 48 which lies within the box cam 3|! a short distance above the roller 36. The lower end of the arm 46 is provided with a slot 49 which receives a pin 50 carried by one of the side walls 5| of a platen carrier. There are two side walls 5| connected by a yoke 52. Extending between the side walls 5| is a pivot shaft 53. The two side walls 5| are provided with downwardly extending arms 54 which carry a shaft 55. Mounted on the shaft 55 are L-shaped levers 56 which carry a shaft 51 on which is mounted a platen 58. A spring 59 pulls the lower end of the levers 56 towards the yoke 52. By this construction it is apparent that the box cam will first operate the inking mechanism to ink the type 63 and immediately after the inking mechanism is withdrawn the platen 58 will be moved beneath the type 43 so as to make a printed impression on an inserted strip or a record strip, which motions would be caused by the lobe 3i and the associated parts of the box cam. This inking and printing would be repeated by the lobe 32 and associated parts of the cam 3|]. If a third printoperation were required, it would be necessary to remove the box cam disk 2| and insert one which was provided with three lobes.

An inserted slip 66 may be inserted through a chute 6| and between a feed roller 62 and an idler roller 63 from whence the paper slip passes above the platen 58 and beneath the printing wheels 43. As is well known in the art, the roller 53 is moved upwardly so as to force the paper against the feed roller 62, after the slip is inserted.

We have provided means to move the slip so as to properly space the slip between the various impressions. Of course, the machine may be operated by the conventional motor or it may be operated by a crank 64 which drives the gear 65 which meshes with and drives a gear 66, which drives a gear 61 secured on a shaft 2'! and which also carries a Geneva gear 58 provided with a set of teeth 69 and a second set of teeth It. As shown, one set of teeth 69 consists of three teeth and the set 10 consists of four teeth. Obviously, the number of teeth in either of these sets may be varied so as to feed the paper any distance desired. The sets of teeth 58 and H3 drive a gear train consisting of pinions H, 12, i3, and 15, which pinion I5 is secured to a shaft 16 which carries the feed roller 62. A holding pawl H is pulled against the teeth of the pinion H by means of a spring 18 to prevent rotation of the gear train unless the gear train is positively actuated by the sets of teeth 69 or 7!].

Instead of using an inserted slip the conventional record strip may be used and the sets of teeth 69 and 10 are so positioned on the Geneva gear 68 so that the set of. teeth 69 will rotate the gear train and feed roller 62 so as to move the paper so as to leave a proper space between a previous impression, if any, and an impression that is now to be made and after the impression is made, the set of teeth 10 will space it the same or a different distance from the first spacing, depending upon the number of teeth in the sets of teeth 69 and I0 and the second impression will now be made. box cam so as to make a third printed impression, it is obvious that a third set of teeth would be provided on the Geneva gear 68.
